Separation performance of -butyl(tetradecyloxy)calix[6]arene as a stationary phase for capillary gas chromatography.

This work presents the first example of the utilization of -butyl(tetradecyloxy)calix[6]arene (C6A-C10) as a stationary phase for capillary gas chromatographic (GC) separation. The statically coated C6A-C10 column showed a column efficiency of 3293 plates per m and had a nonpolar nature. Its selectivity and retention behaviour were investigated using a number of mixtures of diverse analytes and their isomers.

Star-poly(ε-caprolactone) as the stationary phase for capillary gas chromatographic separation.

This work presents the separation performance of star-poly(ε-caprolactone) (star-PCL) as the stationary phase for capillary gas chromatography (GC). The statically coated star-PCL column showed a column efficiency of 3345 plates per m and moderate polarity. Importantly, the star-PCL column exhibited high selectivity and resolving capability for more than a dozen mixtures covering a wide-ranging variety of analytes and isomers.

Performance and selectivity of lower-rim substituted calix[4]arene as a stationary phase for capillary gas chromatography.

This work presents the investigation of -butyl(tetradecyloxy)calix[4]arene (C4A-C10) as stationary phase for capillary gas chromatographic (GC) separations. The statically-coated C4A-C10 capillary column showed weak polarity and column efficiency of 2566 plates per m determined by -dodecane at 120 °C. Impressively, the C4A-C10 column exhibited extremely high resolving capability for a wide range of analytes from nonpolar to polar, including -alkanes, esters, ketones, aldehydes, alcohols and bromoalkanes.
